[QUOTE="chscag, post: 1778150, member: 46727"] Welcome to our forums. Very likely a graphics card failure. The graphics card in your iMac is removable and replaceable, however, it's a very difficult task. The entire display must first be removed and then the logic board removed to get at the graphics card. Those cards are available on eBay but are quite expensive - usually several hundred dollars. As Patrick recommended it might be best to let an authorized Apple tech do the work for you. Be sure to get an estimate first. An Apple Store genius bar will not look at it as it is too old. [/QUOTE]
